SEAL-LOCK.

SPECIFICATION forming part of Letters Patent No. 307,320, datedOct'ober 28, 1884.

Application filed January 17, 1884. (No. model.) I

To @ZZ whom, it may concern.:

Be it known that I, OWEN ENos NEWTON, a citizen of the United States, residing at Fort Madison, in the county of Lee and State of Iowa, have invented certain new and useful Improvements in SeahLoeks, of which the following is a description.

This invention relates to seal-locks for securing freightfcar and other doors, and the invention consists of the novel construction hereinafter described and claimed.

In the drawings, Figurel is a side elevation of my seal-lock, partly in section, also showing a view of the key detached. Fig. 2 is a similar view showing the lock applied to an eyebolt or pin. instead of a hasp or staple.. Fig. 3 is a side elevation, partly broken away, showing my invention adapted to a springkey. Fig. 4 is a similar view showing the lock provided with aprojection whereby it may be driven from the bolt. Fig. 5 is a section on line x :n of Fig. ll, showing a modification by which a leadenshot may be used as a key, and Fig. 6 is an elevation, -partly in section, showing my invention in the form of a padlock.

A indicates the casing of the lock, which may be bolted in suitable position for receiving the pin b, or secured by a chain, O, as shown in Fig. et. In the easing is formed a keyfseat, D, having closed ends E, one or both of which ends may be made flaring outward, and transversely to the key-seat, and on each side of the hole II for pin B is a recess or groove, F, for receiving the ends of the key when the pin is being forced out, as shown in Fig. I. rlhe walls of the recesses F may be beveled ofi at G to facilitate the passage of the key in forcing the pin "from the lock. rIhe pin B has a slot or lateral recess, I, formed in it, which is adapted to register with the keyseat D to receive a wire key, J, which is to be inserted into the closed seat by means of a small aperture, K, leading obliquely thereto. The key consists, preferably, of a straight piece of wire, as shown in F1gs. l and 2; but it may have a loop at one end for attaching a small tag, as shown in Fig. 4, or it may be made of a piece of wire bent double or U- shaped to form a spring, as shown in Fig. 3,

seat. In inserting thelatter the loop end, to which a tag maybe attached, is to enter rst, and when the ends have passed the aperture K they will spring apart into the' flaring recess at the end of the seat, from which they cannot again be extracted through said aperture. apart, the wire key will be bent up or down into the recesses F, the beveled walls G in Figs. 3 and 4.- serving to turn the ends of the key down and t-o guide them into the recesses as the pin B is driven out.

Lindicates the door-hasp, and M the staple, through which the pin B is passed to confine the hasp.

L is an eyebolt or pin, which takes the place ofthe hasp and staple on some cars, the

pin-or bolt being inserted through the door into thejamb, and being locked by the pin B, which passes through its eye into the lock.

M is a staple for securing. thelock in position.

As shown in Fig. 4, the lock may be made comparatively small and inexpensive, in which case it is formed with a shoulder, N, by which it may be driven off the end of the pin B with a hammer. In such case the lock is to be secured by a chain, C, to allow it the necessary movement in removing and replacing the same.

Vhen t-he pin B and the lock are forced The key already described may be used on aperture, I), is formed through the front side i ofthe casing opposite t-o said recess, so that a loaden shot, O, may be dropped therein. The shot will wedge between the wall of the pinseat H andthe beveled surface ofthe recess I, and finally be attened between the pin and its seat in the separation of the pin and lock.

As shown in Fig. 6, the pin B, instead of being straight, may be made U-shaped, and the head may be conlined and adapted to slide in a recess, Q, in the casing A; while the end of the pin is adapted to be secured in the lock in the manner above described.

Instead of inserting the pin B with its point downward, as shown in Figs. 3, 4, 5, and 6, it

IOC

may be reversed in position, and the lock arranged above the hasp or pin L', as shown in Figs. l and This position will always indicate that the pin isloeked, without the necessity of examination. It may be driven ont by hammering on the point.

l do not limit myselt` to any special shape of the lock or means ol" securing it in place, since these may be varied without altering the character ot' the lock.

\Vhat I claim isl. The combination ot' the pin having a re cess or slot formed therein, the lock-casing having a concealed key-seat, with which the slot or recess in the pin maybe 'made to register, and a key adapted to be inserted into the said seat and endwise through the pin through an opening in the easing, substantially as shown and described.

2. The seal-lock having the key-seat l), closed at both ends, and the pin-hole H, the pin-hole being arranged transversely to the key-seat, and recesses or grooves F at the sides ot' the pin-hole, substantially as shown and described.

3. The combination, with a lock-casing having a concealed keyseat, and a recessed pin inserted into the casing of the seal-lock key, consisting of the straight piece of wire cnt of a length corresponding to the length of the key-seat, substantially as shown and described.

4. The combination, with a pin having a slot or recess therein, et' a movable cap-like seal-lock having an internal key-seat, and a straight wire key adapted to enter said keyseat and engage with the pin, substantially as shown and described.

o. rlhe combination, with a pin, ot' a seal lock having an internal or concealed key adapted to engage with the pin, and having a shoulder by which it may be forced from the pin by a hammer, snbstantiall y as shown and described.

(S. rlhe combination, with a pin having a slot or recess therein, of a seal-lock having a keyseat formed with closed ends, and an aperture leading obliquely to said seat, and a key formed of a piece of wire, substantially as shown and described.

't slot or recess therein, of a seal-lock having a key-seat formed with closed ends, and a-n aperture leading obliquely to said seat, and having recesses at the center on opposite sides of the pin-seat, which are provided with beveled walls leading to the pin-seat, and a key formed ot' a piece ot wire, substantially as shown and described.

S. The combination, with a Ushaped pin having a slot or recess therein, ot' a seal-lock casing having a recess for confining the head ofthe pin, whereby the latter may move vertically therein, and having a key-seat formed with closed ends, and an aperture leading obliquely to said seat, and a key formed of ilexiblev metal adapted to engage with the slot in the end ofthe pin, substantially as shown and described.
